Time Zone Planner

Security checks for vulnerabilities and agentic risk

Overview

This skill is a bounded local time-zone planning helper with disclosed limitations and no evidence of hidden access, persistence, or unsafe behavior.

Safe to install for lightweight scheduling support. Users should provide exact IANA time zones or cities for accuracy, and manually confirm DST, availability, and invitations before acting on recommendations.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The code maps the broad region "Asia" to a single time-zone label, "CST (UTC+8)", which imposes one locale-specific convention across a diverse region. This can be considered a natural-language locale policy issue because users are not offered a choice or informed that the skill assumes a specific regional convention.
